joining us is portfolio manager at anc capital. arthur, thanks for joining us. how important are heathrow slots if you want to compete? >> i think they're important to have a presence there and when you look at what delta is doing specifically, they're increasing their scope. and when you look at the flights and the offerings that delta has, it's week relative to american b.a. so what delta wants to do, it smells an opportunity here to give an offer to go customers because this is a network business and move those customers that maybe are going on ba, aa, or united out of newark on o. to the delta large system. and that's the opportunity it has. and conversely people here that want to come to the states or the big network delta has to get people to points beyond i think for virgin to be part of a transaction here, you get the united states market which is a large market. >> you have sink more airlines which would sell, sky team with delta and sort of ba, aa team, as well, how are those three global shaping up, who is winning? >> well, i'm partial to sky team. sk
